Understanding Texas’s approach to contractor licensing is important for anyone offering skilled trade services in the state. While general contracting and handyman work often escape statewide licensing mandates, specialty trades such as HVAC, plumbing, and electrical require specific state-issued credentials. This guide breaks down who needs a license and dives into the detailed requirements for HVAC, plumbing, and electrical contractor licenses in Texas.
Who Needs a Contractor License in Texas?
Not all contractors in Texas must hold a state license. Handymen, general builders, and home improvement specialists can operate without a state-issued credential, though local city or county registrations may still apply.
Specialty trades, however, require licensing through the Texas Department of Licensing and Regulation (TDLR) or other state boards. If your business offers services in any of these areas, a state license is mandatory—even if you don’t formally call yourself a plumber, electrician, or HVAC technician:
- Heating, Ventilation & Air Conditioning (HVAC)
- Plumbing
- Electrical
- Fire sprinkler installation
- Well drilling
- Mold remediation
- Elevator and escalator installation
Municipalities like Austin, Houston, and Dallas often layer additional registration, permit, or inspection requirements on top of state licensing. Always check local regulations before beginning work.

Plumbing Contractor License Details
The Texas State Board of Plumbing Examiners (TSBPE) issues plumbing licenses at multiple levels:
- Master Plumber
- Must hold a valid Texas journeyman plumber license (or equivalent from another state) for ≥ 1 year
- High school diploma or GED
- U.S. citizenship or lawful work authorization
- Supervisory authority over all plumbing work

A Master Plumbing license covers unlimited plumbing—including sanitary drainage, water supply, storm drainage, and gas piping. A Journeyman license covers the same scope but requires direct Master oversight.
To apply, download the appropriate TSBPE application forms, gather experience verifications, proof of education, and citizenship/work authorization documents, then submit to the TSBPE headquarters in Austin along with the required fees.
Electrical Contractor License Details
Any non-exempt electrical work in Texas must be performed by a licensed electrical contractor through the TDLR electricians program. Key requirements include:
- Business Requirements

Texas Contractor License Penalties
- Operating as an unlicensed specialized contractor is a Class C misdemeanor, punishable by fines, administrative fees, and possible jail time.
- HVAC contractors face Class A administrative penalties of $500–$1,000 for violations, and Class B penalties of $1,000–$3,500 plus up to one-year license suspension for serious infractions such as unlicensed activity or recordkeeping failures.
Conclusion
Texas’s decentralized licensing landscape means general contractors enjoy flexibility, but specialty trades face strict state oversight. Whether you plan to install HVAC systems, repipe a building, or rewire a home, securing the appropriate state license is non-negotiable. By following the guidelines above and consulting TDLR or TSBPE directly, you can ensure your business remains compliant, protected, and positioned for growth in one of the nation’s most dynamic construction markets.
